Fawtara · Oman's e-invoicing mandate
Oman's e-invoicing mandate, in plain language
From 2027, Oman requires VAT-registered businesses to issue invoices as structured XML, validated by an accredited Service Provider before it reaches the buyer. No industry is exempt. Here's what it means for your business, and which deadline is yours.
- 1 Apr 2027
- turnover above OMR 5 million
- 1 Oct 2027
- every other VAT-registered business
- XML
- the mandatory invoice format
The mandate
What Fawtara actually requires
“Fawtara” is the brand name of Oman's e-invoicing system, built on the Peppol network's 5-corner model. The legal basis is Oman Tax Authority Decision No. 189/2026, amending the VAT Executive Regulations, published in Official Gazette No. 1660 on 9 August 2026.
It's mandatory, not a pre-approval system
Oman is not building a system where the Tax Authority approves each invoice before it's sent, the way Saudi Arabia's Phase 2 does. Instead: your invoice goes to your own accredited Service Provider, who validates it against Oman's published schema before it moves to the buyer's provider and the buyer. Invoice and tax data reach the Tax Authority in real time for B2B, and within 24 hours for B2C.
You almost certainly don't become the accredited provider
Per the Tax Authority's own FAQ, a business either “identifies and selects an accredited service provider” or, if it wants to, “applies for accreditation itself.” Almost every business takes the first path — it's a normal commercial relationship, not a licence. Becoming an accredited provider yourself is a separate, demanding option (mainland CR with two IT activities, OMR 6,000 paid-up capital, 2 years' operating history, ISO 27001, mandatory Peppol membership) that only makes sense if you want to own the full stack.
There are no industry exemptions
The Tax Authority's FAQ states this directly: “There are no industry exceptions.” The Tax Authority's Chairman can grant limited, individually-requested exemptions in specific cases, but that is a case-by-case waiver, not a category you can fall into by being in a particular sector.
Who, and by when
The dates that matter
Three dates, all confirmed against Decision 189/2026 and the Tax Authority's own FAQ.
August 2026
Pilot cohort (already underway)
A first group of roughly 100 large taxpayers, chosen by revenue, invoice volume and technical readiness. The Tax Authority commits to notifying each participant at least 6 months before their own onboarding date — if that's you, follow the date in your own notice, not this page.
1 April 2027
Annual supplies above OMR 5,000,000
Mandatory for every taxable person whose annual supplies exceed OMR 5 million — regardless of sector.
1 October 2027
Every other VAT-registered taxpayer
Mandatory for all remaining VAT-registered taxpayers — i.e. everyone at or above Oman's mandatory VAT registration threshold who isn't already covered by the April date.
Below OMR 38,500? You're not in scope — yet
The mandate only ever reaches VAT-registered taxpayers. Oman's mandatory VAT registration threshold is OMR 38,500 of annual taxable turnover (voluntary registration is open from OMR 19,250). A business below the mandatory threshold sits outside the e-invoicing mandate, at every phase, unless it has voluntarily registered for VAT.
There are no industry exemptions
The Tax Authority's FAQ states this directly: “There are no industry exceptions.” The Tax Authority's Chairman can grant limited, individually-requested exemptions in specific cases, but that is a case-by-case waiver, not a category you can fall into by being in a particular sector.

What you must do
Getting ready, step by step
1. Choose an accredited Service Provider
Per the Tax Authority's FAQ: “E-invoices can be issued through any compliant e-invoicing solution. All e-invoices issued must be validated by the issuer's respective accredited service provider.” This is a commercial relationship you set up, not a licence you apply for.
2. Make sure your software can produce the format
XML is the mandatory structured format, per the Tax Authority's FAQ verbatim: “Invoices must be issued in XML format as the mandatory structured format.” The specific schema is PINT OM — Oman's own localisation of Peppol's International Invoice Model. Your invoicing or accounting software needs to generate this, either natively or through an add-on layer; this is usually the actual integration work.
3. Prepare invoice numbering and the B2C QR code
A unique invoice number is a statutory requirement. Every B2C invoice needs a QR code, generated by the seller, on the human-readable copy — it isn't required inside the XML itself. Consolidated or batch invoices aren't allowed for B2C: one e-invoice per transaction. Paper invoices aren't abolished, but after go-live they're only permitted as an accompaniment to the mandatory electronic format for B2C.
4. Know what “validated” actually means
Your accredited Service Provider checks that your invoice is well-formed and complete against Oman's published schema before it moves on — that is a structural check, not the same thing as the Tax Authority accepting the invoice in production. TechMate is a systems integrator, not an OTA-accredited Service Provider: we help you get your invoicing software ready and connect you to an accredited provider — we don't verify VAT numbers, detect duplicate invoices, or guarantee OTA acceptance, because those checks require live accredited access we don't have.
The XML format
What “XML is mandatory” means in practice
You will not be typing XML by hand, and neither will your staff. XML is what your invoicing software sends behind the scenes — a structured, machine-readable version of the invoice, built to Oman's PINT OM schema (a Peppol standard based on the international UBL format). What changes for your team is upstream of that: the software you use has to be able to produce it.
In practice, that means one of three things: your current software already supports it (check with your vendor), your vendor can add it, or you'll need a layer that sits alongside your existing system and generates the compliant XML from the invoices you already create. Whichever software you use, the Tax Authority's own FAQ is clear that the compliance step itself — validating that XML against the schema — sits with your accredited Service Provider, not with your software vendor.
Frequently asked
Questions every business asks first
Do I need to comply with Oman's e-invoicing mandate?
Only if you're VAT-registered (or become VAT-registered later). Below Oman's mandatory VAT registration threshold of OMR 38,500 in annual taxable turnover, the mandate doesn't reach you — use the checker above to see where you stand.
What is the e-invoicing deadline in Oman?
1 April 2027 for businesses with annual supplies above OMR 5 million; 1 October 2027 for every other VAT-registered business. A pilot cohort of roughly 100 large taxpayers has been onboarding individually since August 2026.
What happens if I don't comply?
We haven't found a published penalty figure for this specific mandate in any primary Tax Authority source, so we won't invent one here. What is certain is the deadline itself, and that the Tax Authority states plainly there are no industry exemptions — non-compliance is a legal and VAT-compliance risk worth planning around well before your date, not a wait-and-see question.
Does my current software already support this?
Maybe — check directly with your vendor whether it can generate PINT OM XML and route it through an accredited Service Provider. If it can't, that's exactly the gap we help close: either by extending what you have or adding a layer that produces the compliant format from your existing invoices.
Do I need to become an accredited Service Provider myself?
No — almost no business needs to. The standard path is choosing one of the already-accredited providers to validate and transmit your invoices, a normal vendor relationship. Becoming a provider yourself is a separate, demanding route (mainland CR with two IT activities, OMR 6,000 paid-up capital, ISO 27001, mandatory Peppol membership) meant for companies that want to own that layer for others, not simply comply themselves.
Can a check tell me my invoice will be accepted?
A structural check can tell you your invoice is well-formed and complete against the published schema. It cannot tell you the Tax Authority will accept it in production — that confirmation only happens inside the real, live accredited-provider network, which is a different thing from a standalone check. Be wary of anyone who tells you otherwise.
